■Stopping the engine
Shift the shift lever to P and press the engine switch as you normally do when stop-

tomization setting. If it is off, turn the function on.

■When recharging or replacing the battery
●For vehicles with an alarm: make sure that the key is not inside the vehicle when
recharging or replacing the battery. The key may be locked in the vehicle if the
alarm is activated. (→P. 88)
●In some cases, it may not be possible to unlock the doors using the smart entry &
start system when the battery is discharged. Use the wireless remote control or the
mechanical key to lock or unlock the doors.
●The engine may not start on the first attempt after the battery has recharged but
will start normally after the second attempt. This is not a malfunction.
●The engine switch mode is memorized by the vehicle. When the battery is recon-
nected, the system will return to the mode it was in before the battery was dis-
charged. Before disconnecting the battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery dis-
charged, be especially careful when reconnecting the battery.
CAUTION
■Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flammable
gas that may be emitted from the battery:
●Make sure each jumper cable is connected to the correct terminal and that it is
not unintentionally in contact with any other than the intended terminal.
●Do not allow the other end of the jumper cable connected to the “+” terminal to
come into contact with any other parts or metal surfaces in the area, such as
brackets or unpainted metal.
●Do not allow the + and - clamps of the jumper cables to come into contact with
each other.
●Do not smoke, use matches, cigarette lighters or allow open flame near the bat-
tery.
